During the last half century has increased dramatically, primarily energy consumption. If the trend continues until 2030. year will need another planet.

INVESTIGATION World Fund for Nature shows that humanity has for years not living in accordance with the possibilities. During the last half century has increased dramatically, primarily energy consumption. If the trend continues until 2030. year will need another planet!

Negative trends exist in multiple "fronts": on average, each resident spends one planet and a half times more than what nature can provide him. In industrialized countries the consumption is several times higher.

Then, one billion people lack drinking water. Since the seventies, then, in the world, a third, reduced the strength of the 2500 observed species in the tropics reduction is as high as two thirds! Seventy percent of all fish species endangered due to over-catch.

If the area of ​​the country was divided fairly and according to what nature can provide, each person would have a useful area of ​​1.8 global hectares. Since the seventies, however, consumption of humanity greatly exceeds the annual biocapacity countries to use 2.7 global hectares per capita. It is one and a half times more than what nature can provide.

In the last half century has drastically increased primarily energy consumption. It is growing rapidly and continues in countries such as China, India, Brazil and Russia.

- To meet the demand for food, energy and other natural resources is already practically need a different planet - said Eberhard Brandes from the German branch of the World Fund for Nature. - The prosperity in the developed world has paid the biological richness of other parts of the world, among others, tropical regions.

This is reflected in the human environment - in tropical areas the numbers of species, which are monitored, reduced by 60 percent in the moderate climate of 29 percent. Branders also showed a photograph - of the tropical forest in Sumatra, was set up camera-trap, which was supposed to save the tiger. The photograph shows bulldozer which clears a forest ...

How much who have

Especially luxurious living in the United Arab Emirates, where everyone has ten acres, and "belongs to him," and on the planet every 1.8 acres. Followed by Denmark, Belgium and the United States. Germany has five global hectares somewhere in the middle. On the back of East Timor, Bangladesh and Afghanistan with 0.5 global hectares. So a man already consumed by half biocapacity more than what is available. In addition, most developed countries live at the expense of underdeveloped countries and rapid development.

Skull and tusks of enormous primitive elephant, who died two million years ago, they found construction workers in Chile. Mastodon, the approximate size of today's elephants, probably lived in forests and plains, before it died and sank into the swamp, which has preserved its remains.

Found parts of animals could help scientists to gather more information about the DNA that share the elephants with their much larger cousins, woolly mammoth. It could also be gathered to new discoveries about the origin of elephants.

To the skull and tusks came up during the construction of hydropower plants along the river near the capital of Chile, Santiago. Digging into the depth, the workers noticed 121 centimeters long and 15.24 wide tusks. Then they called paleontologists, who after further digging, found the first complete skull of a mastodon.

When we started digging, we realized that there is something else besides the tusks - says Rafael Labarca the Chilean Institute. - The entire skull is of one piece and in perfect condition, with all the teeth and tusks. Within the skull, we found part of the vertebra, which was once part of the spine.

Mastodon were great as today's elephants, but they had more muscle and fur, which protected them from cold. Fossil evidence shows that they lived in Africa about fifty million years.

First animals, which resembled pigs with tusks, have evolved into a series of new species. Some of them were much larger, spread across the globe, settling every continent except Australia and Antarctica. Trilofodon with four tusks, appeared before 26 million years ago and lived up to two million years ago in Eurasia, Africa, and North America.

Modern humans are, by comparison, began to inhabit the planet 200,000 years ago.

Evolution and extinction of most modern species of elephants, were connected, presumably, with the spread of the human race. Most of the remains of mastodon, found in North America.

Few are found in the southern part of the continent. One of the greatest discoveries occurred 1993rd in Diamond Velija, lake outside Hemet, California. There is a lot of remains found, then this place is named Valley of the mastodons.

In July 2007. The west of Athens, were discovered mastodon tusk length 4.8 meters, each weighing a ton.

MAMMOTH - the next of kin the largest of all elephants, mammoth, which was accustomed to cold in Eurasia, Africa and North America, two million years ago. It is believed that these animals are the closest relatives of modern elephants. Mammoths and mastodons, they lived up to two million years ago, and is considered to have been the first known people.

The Japanese managed to create an artificial uterus from acrylic, and the Americans into practice the idea of ​​creating an artificial uterus from human cells. Implementation of this project to people is expected over the next five years.

World in due time may not walk pregnant men, although scientists are trying to implement in practice what is Arnold Schwarzenegger, an upset stomach "to the teeth," demonstrated in the movie "Junior", but the baby, according to how far advanced research, for the most five years will be able to grow - in artificial wombs.In three of the world's center is currently working on three ideas about creating an artificial womb, and women who have no uterus, giving hope to be able to become mothers.

- Scientists at the University "May Tent" in Japan, the longest work on this project, they managed to create an artificial womb incubator of 40 to 25 inches, with synthetic amniotic fluid (artificial fetus with water) and a system that provides sufficient oxygen and nutrients for life fruit - explains Dr. Slobodan Radulovic, an obstetrician gynecologist. - In utero incubator, made of special plastic, acrylic, physics and chemistry is absolutely neutral, raised by several offspring animals, mostly goats. In such an environment, the offspring were increased more than 10 days, and scientists hope that by the end manage to make an artificial womb.Researchers' Kirnel "universities in America different technique - culturing lining of the uterus outside the body, women were given several layers of mucous membrane of sufficient width to create an artificial womb. Their idea is to create an artificial uterus from human cells and embedded in a woman's body. The most significant project is implemented in the "Temple" University in the USA, where he went the furthest in the creation of artificial amniotic fluid, in which the fruit can not live without harmful effects, which is a project about the artificial uterus important.

- The highest use of an artificial womb, when the project comes to life the people, will have in premature babies who are too young for the incubator - says Radu. - A baby who is born after 24 weeks of pregnancy has become routine to modern medicine can preserve life, but a problem if the baby is born before. Artificial womb would be held in the life of a baby born at 15 weeks. It would be up to 24 weeks of growing in an artificial womb, and then in the incubator. Women due to primary diseases, such as women on dialysis, unable to carry the child, with the artificial womb may be born child.

If the practice achieve Japanese design artificial uterus in the foreseeable future will be found among "classic" incubators in hospitals, and comes to life when the idea of ​​U.S. researchers implant women are routinely, as is now transplanted kidneys or hearts.

- It is assumed that this will revitalize itself in people over the next five years - says Radu. - Artificial uterus is a logical continuation of the development of medicine in this Moraga. It will cause resistance to the public, as was resistance against the first test-tube babies. 20 years ago, a tremendous roar of opposition caused the project test-tube baby, and so far in the world in this way was born more than a million children.

Babies could soon be fed with human milk, which is a product of genetically modified cows. Scientists have bred 300 animals that were given human genes, in order that their milk contains the same nutrients and fats such as from human breast milk, according to Daily Mail. Scientists believe that the product is genetically modified cows could be an alternative to the conventional formula to mothers for food for children.

However, scientists have condemned the move by critics who question the safety of this method.

Human milk differs from cow in that it contains large amounts of nutrients, which are beneficial for growth and immune system of babies. Cow's milk has less fat and less carbohydrates, and contains antibodies that protect against disease.

Professor Li Ning, who led the research at the Chinese University of Agriculture, said that the milk of genetically modified cows milk as safe as ordinary.

"Milk modified cow has a stronger taste than usual. For ten years people will be able to buy in the supermarket," said Li.

"We have to make some rules that will serve to preserve human health. This milk could pose a risk to us is not yet known. Cow's milk will never be like a human," said Patty Randall, member of the campaign, "Baby Milk Action."

Professor Li and his team used the technology of cloning using human genes that are instilled into the DNA of Holstein cows.

The third human protein alpha-lactalbumin is also present in milk. Professor Li said that his team had increased the amount of fat in cow's milk by a fifth, and that it has done very similar to human.

Critics, however, argue that the growing of genetically modified cows negative to animals. In two experiments in China in which 42 cows were born, they survived only 26th Ten of them died after birth, and six more in the next six months.

Rules in China relating to genetically modified foods are less strict than European. British scientists believe that this research could be very useful.

Modified milk could improve sales cows in Asia, where nine out of ten people do not tolerate lactose, so they can not consume cow's milk, and later do not suffer from stomach aches and cramps.
